A load control system may be commissioned using beacons. The load control system may include control devices that each include a beacon transmitting circuit configured to transmit a beacon that comprises an identifier associated with the control device. A network device, such as a mobile device, may discover a control device based on the beacon received from the control device. In response to discovery of the control device, the control device may be added to a temporary group of control devices for being collectively configured and/or controlled. Control devices may be discovered based on the signal strength at which the beacons are received. The control devices may provide feedback to a user in response to confirmation messages to indicate to a user that the lighting control device has been added to the temporary group. The control devices may stop providing the feedback after they are removed from the temporary group.

Commissioning and controlling load control devices

An apparatus includes a first terminal, a second terminal, a bi-directional regulator circuit, and functional circuitry. The bi-directional regulator circuit generates a voltage across a first power supply node and a second power supply node in response to an input current flowing through the first terminal and the second terminal with a first polarity. The bi-directional regulator circuit also generates the voltage across the first power supply node and the second power supply node in response to the input current flowing through the first terminal and the second terminal with a second polarity opposite the first polarity. The functional circuitry is powered by the voltage and is configured to generate a signal using the voltage. The signal is indicative of the input current in response to the input current being supplied to the first terminal and is indicative of the input current in response to presence of the input current.

Isolator including bi-directional regulator

An analog signal is transported across an isolation channel using edge modulation/demodulation of a pulse width modulated (PWM) signal. An edge modulator is responsive to rising edges of the PWM signal to generate first pulses having a first predetermined pulse width and is responsive to receipt of falling edges of the PWM signal to generate second pulses having a second predetermined pulse width with the same polarity as the first pulses. On the opposite side of the isolation channel an edge demodulating circuit recreates the PWM signal using the first and second pulses. The rise and falling edges of the PWM signals can be distinguished based on the pulse width of the first and second pulses. A second order pulse width modulator may be used to generate the PWM signal.

Transport of an analog signal across an isolation barrier

A first integrated circuit die receives input data from a plurality of input channels and combines the input data from the plurality of input channels into combined data. The first integrated circuit die transmits the combined data across an isolation communication channel. A second integrated circuit die that is coupled to the isolation communication channel decodes the transmitted combined data and supplies the decoded transmitted combined data to respective output channels corresponding to the input channels.
